Cavener and Clegg measured the viability of the different Adh genotypes in the alcohol environment and obtained the following values: Genotype Relative viability AdhF/AdhF 0.932 AdhF/AdhS 1.288 AdhS/AdhS 0.596 If a population has an initial frequency of p = f (AdhF) = 0.5, what will the expected frequency of AdhF be in the next generation on the basis of the fitness value you calculated?

Step 1
Step 1: Calculate the expected frequency of AdhF in the next generation using the Hardy-Weinberg equation: \[p^2 + 2pq + q^2 = 1\] where p = frequency of AdhF, q = frequency of AdhS, and 2pq = frequency of AdhF/AdhS. Show more…

The relative fitness values of three genotypes are wA/A = 1.0, wA/a = 1.0, and wa/a = 0.7. a. If the population starts at the allele frequency p = 0.5, what is the value of p in the next generation? b. What is the predicted equilibrium allele frequency if the rate of mutation of A to a is 2 × 10^(-5)?

The relative fitness values of three genotypes are $w_{A / A}=$ $1.0, w_{A / a}=1.0,$ and $w_{a / a}=0.7$ a. If the population starts at the allele frequency $p=$ $0.5,$ what is the value of $p$ in the next generation? b. What is the predicted equilibrium allele frequency if the rate of mutation of $A$ to $a$ is $2 \times 10^{-5}$ ?
1. a. If the frequencies of alleles A and a are 0.2 and 0.8, respectively, what are the frequencies of the genotypes AA, Aa, aa expected to be at Hardy-Weinberg equilibrium? b. In a population with those genotypic frequencies, suppose that the fitnesses of the genotypes AA, Aa, aa are, respectively, 0.8, 1.0 and 1.0. What is the value of average fitness in the population? c. Given the values just calculated, how much do you expect the frequency of the A allele to change in one generation?
